Smoke Alarm Troubleshooting

Nuisance alarms are usually caused by dust, insects, steam, humidity or cooking smoke rather than an actual fire. Vacuum gently around the alarm and clear any obvious environmental causes first. If it keeps activating after that, the unit may be faulty or nearing the end of its life and should be professionally inspected or replaced.

A regular chirp or beep usually points to a low or flat battery, a fault, a power issue, or an alarm that has reached the end of its service life. Check the battery and the manufacturer's troubleshooting steps first. If the beeping continues, have it checked by a qualified technician.

Test your smoke alarms regularly in line with the manufacturer's instructions. We recommend following the maintenance schedule that came with your system and confirming each alarm sounds correctly when tested.

Keep alarms free of dust and insects, as build-up can affect how they operate. Vacuum gently around each unit and follow the manufacturer's cleaning guidance as part of your regular maintenance.

Smoke alarms have a limited service life and must be replaced once they reach their age limit or stop working properly. If yours are getting old or faulty, it's worth arranging a replacement.

A professional inspection is worthwhile if you're selling, have recently upgraded, are having ongoing issues, or aren't sure your alarms meet the requirements for your home. Our team can inspect, service and resolve any problems.
